skypixel [1] filed a deletion request for fsharp-git [2]: This package is no longer necessary: the official repository for fsharp has been changed to be https://github.com/dotnet/fsharp and the dependencies have changed too. F# compiler is officially shipped only through the dotnet distribution. [1] https://aur.archlinux.org/account/skypixel/ [2] https://aur.archlinux.org/pkgbase/fsharp-git/
